Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Dichtungsanordnung nach der Gattung des Patentanspruchs 1.The invention is based on a sealing arrangement according to the preamble of patent claim 1.

Es ist schon eine derartige Dichtungsanordnung bekannt ( DE 195 35 235 A1 , DE 19736431 A1 , bei der eine Abdeckhaube eines Hydraulikaggregats am freien Rand ihrer Außenwand eine umlaufende Nut aufweist, in der eine separat spritzgeformte, gummielastische Dichtung mit Dichtlippen einliegt. Die Nut ist durch unterschiedliche hohe Nutwangen begrenzt: eine zur Außenseite der Wand gelegene Nutwange ist höher als eine innenseitige Nutwange. Die äußere Nutwange greift flächig an einer ebenen Stirnseite eines Ventilblocks des Hydraulikaggregats an. Die innere Nutwange greift mit ihrer ebenen Stirnfläche an der Dichtung an und hält deren Anlage am Ventilblock aufrecht. Während die gummielastische Dichtung den Innenraum der Abdeckhaube statisch abdichtet, soll die äußere Nutwange das Vordringen z. b. eines Dampfoder Wasserstrahls eines Hochdruckreinigungsgeräts zur Dichtung verhindern. Wegen Fertigungs- oder Montagetoleranzen ist jedoch ein flächiger Angriff der äußeren Nutwange entlang der gesamten Länge der Außenwand der Abdeckhaube nicht immer sichergestellt.It is already known such a sealing arrangement ( DE 195 35 235 A1 . DE 19736431 A1 in which a cover of a hydraulic unit at the free edge of its outer wall has a circumferential groove in which rests a separately injection-molded, rubber-elastic seal with sealing lips. The groove is limited by different high groove cheeks: a groove cheek located to the outside of the wall is higher than an inside groove cheek. The outer groove cheeks engage flat against a flat end face of a valve block of the hydraulic unit. The inner groove cheek engages with its flat face on the seal and keeps their investment on the valve block upright. While the rubber-elastic seal statically seals the interior of the cover, the outer groove cheek should prevent the penetration zb a steam or water jet of a high-pressure cleaner for sealing. Because of manufacturing or assembly tolerances, however, a surface attack of outer groove cheek along the entire length of the outer wall of the cover is not always ensured.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Dichtungsanordnung mit den Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, dass durch die Verformung des nasenförmigen Vorsprungs Toleranzen zwischen den beiden Teilen des Aggregats auf einfache Weise ausgeglichen werden können, während die keilförmige Nutwange ein Auswandern der Dichtung erschwert. Es wird also zum einen mittels des nasenförmigen Vorsprungs an der außenseitigen Nutwange ein sicherer Verschluss eines Spalts zwischen den Teilen des Aggregats gegen das Eindringen von Flüssigkeiten oder Fremdkörpern erzielt, zum anderen wird mittels der keilförmigen Nutwange die Dichtung weitgehend in der Nut zurückgehalten, so dass sie einer hohen Pressung unterworfen werden kann, was ihre Dichtwirkung unterstützt. Dennoch kann ein Teilvolumen der Dichtung die keilförmige Nutwange überwinden, damit die beiden Teile des Aggregats einander soweit angenähert werden können, damit ein Auftreffen des nasenförmigen Vorsprungs auf seine Gegenfläche erfolgt. Dabei verhindert die abgerundete Spitze an der keilförmigen Nutwange ein Abscheren des aus der Nut verdrängten Teilvolumens der Dichtung.The seal assembly according to the invention with the features of claim 1 has the advantage that tolerances between the two parts of the unit can be compensated in a simple manner by the deformation of the nose-shaped projection, while the wedge-shaped groove cheek makes emigration of the seal difficult. On the one hand, by means of the nose-shaped projection on the outside groove cheek, a secure closure of a gap between the parts of the assembly against the ingress of liquids or foreign bodies is achieved, on the other hand the seal is largely retained in the groove by means of the wedge-shaped groove cheek, so that they can be subjected to a high pressure, which supports their sealing effect. Nevertheless, a partial volume of the seal overcome the wedge-shaped groove cheek, so that the two parts of the unit can be approximated as far as possible, so that an impact of the nose-shaped projection takes place on its counter surface. The rounded tip on the wedge-shaped groove cheek prevents shearing off of the groove displaced partial volume of the seal.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Patentanspruch 1 beschriebenen Dichtungsanordnung gegeben.The measures listed in the dependent claims advantageous refinements and improvements of the seal assembly described in claim 1 are given.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung vereinfacht dargestellt. Es zeigen Figur 1 eine Ansicht auf einen als Deckel ausgebildeten Teil eines Aggregats mit einer stirnseitigen, umlaufenden Dichtungsanordnung, Figur 2 einen Schnitt entlang der Linie II-II in Figur 1 durch die Dichtungsanordnung des Deckels, in vergrößertem Maßstab, und Figur 3 einen Schnitt entsprechend Figur 2 mit an einem anderen Teil des Aggregats angebrachtem Deckel.An embodiment of the invention is shown in simplified form in the drawing. Show it FIG. 1 a view on a formed as a lid part of an aggregate with a frontal, circumferential seal assembly, FIG. 2 a section along the line II-II in FIG. 1 by the sealing arrangement of the lid, on an enlarged scale, and FIG. 3 a cut accordingly FIG. 2 with lid attached to another part of the unit.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Ein in Figur 3 der Zeichnung nur abschnittsweise wiedergegebenes Aggregat 10 besteht aus zwei Teilen 11 und 12, von denen der als Deckel ausgebildete Teil 11 mit einer Dichtungsanordnung 13 versehen ist. Der andere Teil 12 des Aggregats 10 ist ein Ventilblock mit einer ebenen Fläche 14 für den Angriff der Dichtungsanordnung 13.An in FIG. 3 The drawing only partially reproduced unit 10 consists of two parts 11 and 12, of which the part 11 formed as a cover is provided with a seal assembly 13. The other part 12 of the unit 10 is a valve block with a flat surface 14 for the attack of the seal assembly thirteenth

Der in Figur 1 vor der Montage am Teil 12 dargestellte Teil 11 hat eine umlaufende Wand 16, welche an ihrer Außenseite 17 mit flanschartigen Ansätzen 18 sowie Befestigungslöchern 19 in den Ansätzen für eine in der Zeichnung nicht wiedergegebene Verschraubung des Teils 11 am Teil 12 ausgestattet ist. Die Dichtungsanordnung 13 ist an der Stirnseite dieser Wand 16 ausgebildet. Die Wand 16 hat eine entlang der Stirnseite verlaufende, gegen den Teil 12 offene Nut 20, deren ebener Grund 21 parallel zur Fläche 14 des Teils 12 verläuft (Figuren 2 und 3). Die Nut 20 ist zur Außenseite 17 der Wand 16 hin durch eine Nutwange 22 begrenzt. Unmittelbar angrenzend an die Nut 20 ist an die Nutwange 22, ausgehend von deren freier Stirnseite, ein nasenförmiger Vorsprung 23 mit relativ schlankem Querschnitt angeformt. Der entlang dem gesamten Umfang der Wand 16 verlaufende, nasenförmige Vorsprung 23 trägt zu einem kleinen Teil an der Höhe der Nutwange 22 bzw. der Tiefe der Nut 20 bei. Auf der Innenseite 24 der Wand 16 ist die Nut 20 durch eine Nutwange 25 begrenzt, welche, ausgehend vom Grund 21, höchstens bis zur halben Nuttiefe aufragt bzw. maximal die halbe Höhe der Nutwange 22 erreicht. Die innenseitige Nutwange 22 ist im Querschnitt als Keil ausgebildet, welcher mit seinem einen Schenkel fluchtend zur Wand 16 verläuft. Die Nutwange 22 hat eine abgerundete Spitze und verläuft mit ihrem anderen Schenkel unter einem Keilwinkel von etwa 45° in den Grund 21 der Nut 20 aus. Die Nutwange 25 erstreckt sich, ebenso wie die Nutwange 22, entlang dem gesamten Umfang der Wand 16 des Teils 11, das aus einem glasfaserverstärkten Thermoplast spritzgegossen ist.The in FIG. 1 Part 11 shown prior to assembly on part 12 has a peripheral wall 16 which is provided on its outer side 17 with flange-like lugs 18 and mounting holes 19 in the lugs for not shown in the drawing screwing of the part 11 on the part 12. The seal assembly 13 is formed on the end face of this wall 16. The wall 16 has a groove 20 which extends along the end face and is open against the part 12, the plane base 21 of which runs parallel to the surface 14 of the part 12 ( FIGS. 2 and 3 ). The groove 20 is limited to the outside 17 of the wall 16 through a groove cheek 22. Immediately adjacent to the groove 20 is formed on the groove cheek 22, starting from the free end face, a nose-shaped projection 23 with a relatively slender cross-section. The along the entire circumference of the wall 16 extending, nose-shaped projection 23 contributes to a small part of the height of the groove cheek 22 and the depth of the groove 20 at. On the inside 24 of the wall 16, the groove 20 bounded by a groove cheek 25, which, starting from the base 21, at most extends to half the groove depth or reaches a maximum of half the height of the groove cheek 22. The inside groove cheek 22 is formed in cross-section as a wedge, which runs with its one leg in alignment with the wall 16. The groove cheek 22 has a rounded tip and extends with its other leg at a wedge angle of about 45 ° in the base 21 of the groove 20. The groove cheek 25 extends, as does the groove cheek 22, along the entire circumference of the wall 16 of the part 11 which is injection molded from a glass fiber reinforced thermoplastic.

In der Nut 20 der Wand 16 ist eine umlaufend in sich geschlossene, gummielastische Dichtung 27 angeordnet. Diese besteht aus Silikonkautschuk, welcher aus einem von einem Manipulator geführten Spender in die Nut 20 eingebracht ist. Die nach dem Aushärten des Silikonkautschuks im Wesentlichen inkompressieble Dichtung 27 weist die in Figur 2 wiedergegebene Kontur auf. Die Dichtung 27 hat einen die Nut 20 ausfüllenden sowie in unbelastetem Zustand die beiden Nutwangen 22 und 25 etwa halbkreisförmig überragenden Querschnitt (Fig. 2).In the groove 20 of the wall 16 is a circumferentially self-contained, rubber-elastic seal 27 is arranged. This consists of silicone rubber, which is introduced from a guided by a manipulator dispenser in the groove 20. The after curing of the silicone rubber substantially incompressieble seal 27 has the in FIG. 2 reproduced contour. The seal 27 has a groove 20 filling and in the unloaded state, the two groove cheeks 22 and 25 approximately semicircular superior cross section ( Fig. 2 ).

Zur Montage wird das Teil 11 auf das Teil 12 aufgesetzt und mit diesem verschraubt. Während der dabei erfolgenden Annäherung des Teils 11 an die Fläche 14 des Teils 12 wird die gummielastische Dichtung 27 verformt und in Richtung auf den Grund 21 der Nut 20 zurückgedrängt. Dabei wird auch ein Teil ihres Volumens aus der Nut 20 zur Innenseite 24 der Wand 16 hin verdrängt (Figur 3). Im weiteren Verlauf der Verschraubung trifft der nasenförmige Vorsprung 23 der Nutwange 22 auf die Ebene 14 des Teils 12 auf und unterliegt einer plastischen Verformung. Die Verschraubung wird abgeschlossen, wenn sichergestellt ist, dass unter Berücksichtigung von Fertigungs- und Formtoleranzen der Vorsprung 23 unter plastischer Verformung über die gesamte Länge der Wand 16 an der Fläche 14 des Teils 12 angreift. Während des Verschraubens übt die Nutwange 25 einen sich mit Annäherung an die Fläche 14 vergrößernden Widerstand gegen das seitliche Ausweichen der Dichtung 27 aus der Nut 12 aus. Dies hat zur Folge, dass mit kleiner werdendem Abstand zwischen der Spitze der Nutwange 25 und der Fläche 14 des Teils 12 eine sich verstärkende Pressung des in der Nut 20 befindlichen Volumens der Dichtung 27 erfolgt, was deren Dichtwirkung erhöht. Dabei verhindert die Form der Nutwange 25 eine Abscheren des aus der Nut 20 verdrängten Teilvolumens der Dichtung 27.For assembly, the part 11 is placed on the part 12 and screwed to it. During the approach of the part 11 to the surface 14 of the part 12, the rubber-elastic seal 27 is deformed and pushed back in the direction of the base 21 of the groove 20. In this case, a part of its volume is displaced out of the groove 20 towards the inside 24 of the wall 16 ( FIG. 3 ). In the further course of the screwing the nose-shaped projection 23 of the groove cheek 22 strikes the plane 14 of the part 12 and is subject to plastic deformation. The screwing is completed when it is ensured that under Considering manufacturing and form tolerances of the projection 23 under plastic deformation over the entire length of the wall 16 on the surface 14 of the part 12 attacks. During screwing, the groove cheek 25 exerts an increasing resistance to lateral deflection of the seal 27 out of the groove 12 as it approaches the surface 14. This has the consequence that with decreasing distance between the tip of the groove cheek 25 and the surface 14 of the part 12 is a reinforcing pressing of the groove 20 located in the volume of the seal 27 takes place, which increases their sealing effect. The shape of the groove cheek 25 prevents shearing off of the partial volume of the seal 27 displaced from the groove 20.

Die Gesamtwirkung der Dichtungsanordnung 13 besteht aus zwei Einzelwirkungen: zum einen dichtet der plastisch an der Fläche 14 des Teils 12 verformte Vorsprung 23 und zum anderen die gummielastische Dichtung 27 durch Angriff an der Fläche 14 ab. Der zur Außenseite der Wand 16 gelegene Vorsprung 23 verhindert als Element der Dichtungsanordnung 13 beispielsweise das Vordringen eines Dampf- oder Wasserstrahles eines Hochdruckreinigungsgerätes zur gummielastischen Dichtung 27. Diese das zweite Element der Dichtungsanordnung 13 bildende Dichtung 27 verhindert aufgrund ihrer hohen Pressung ein Unterwandern von Flüssigkeiten oder Fremdstoffen zur Innenseite 24 der Wand 16 hin. Die Dichtungsanordnung 13 wird hohen Beanspruchungen gerecht, wie sie beispielsweise bei Aggregaten auftreten, die in einem Motorraum eines Fahrzeugs angeordnet sind.The overall effect of the sealing arrangement 13 consists of two individual effects: on the one hand, the protrusion 23 plastically deformed on the surface 14 of the part 12 and, on the other hand, the rubber-elastic seal 27 seals against the surface 14 by attack. The located to the outside of the wall 16 projection 23 prevents as an element of the seal assembly 13, for example, the penetration of a steam or water jet of a high-pressure cleaner for rubber-elastic seal 27. This the second element of the seal assembly 13 forming seal 27 prevents underflowing of liquids due to their high pressure Foreign matter to the inside 24 of the wall 16 back. The seal assembly 13 is high demands, such as occur in aggregates, which are arranged in an engine compartment of a vehicle.
